nothing wrong with the shortness of left leg if you just move this to right and make the leg looking more on front. so you'd get an impression that she is going out of the image hehe. foreshortening and such

If you alternately use big soft brushes and hard brushes you can get the effect of shadows and value transitions with some gradients in the middle. That's what i notice in comics a lot. It would be interesting if the lights from above were a different color by the way. You can have a nice warm/cool setup for instance._________________It's nice to be important, but more important to be nice - Scooter
